Who invented the meter ruler?

The meter ruler was not invented by a single individual, but rather was established as a unit of measurement by the French Academy of Sciences in the late 18th century. The meter was originally defined as one ten-millionth of the distance from the North Pole to the Equator along a meridian passing through Paris. The meter ruler, a physical representation of this unit of length, has since become a standard tool for measuring length in the metric system.
